Every single physical core on the chip decodes and executes both s390x and Arm AArch64 instructions, dynamically switching between the two ISA modes and convert them into micro ops. Mode switching is hypervisor-driven.
And those chips are fast. 5.7 Ghz 2nm node.
For who: When you need to run Linux programs on high security, mission critical environment. Others should not care.
